专利号:US-9920160-B2 优先权日:2014-09-03 标题 :Method for synthesis of polymer containing multiple epoxy groups 发明人:GAO CHAO; ZHENG YAOCHEN; PENG LI; CAI SHENGYING; WENG ZHULIN 权利人:UNIV ZHEJIANG 摘要:A method for a synthesis of a polymer containing multiple epoxy groups includes steps of: under protection of nitrogen or argon, with a photosensitive free radical initiator under an ultraviolet light irradiation, initiating a mixture of a dithiol compound and alkynyl glycidyl ether or other alkynyl-containing compounds to proceed a thiol-yne polymerization, so as to obtain the polymer. The number of the epoxy groups is able to be adjusted through changing a type of a dithiol monomer, a mixing ratio of the dithiol monomer, and a mixing ratio between the alkynyl glycidyl ether and other alkynyl compounds. The present invention has advantages of: fast reaction, convenient process, easy post-processing, a large number of the epoxy groups, and adjustable and controllable content. The obtained polymer has a wide potential application in fields of coating, adhesive, ink, encapsulating material, resin for composite material, additive, high performance material, function material, and so on.

In particular, transition metal (e.g. Co, Ni, Fe, Mo) complexes of diarylacetylenes, e.g. diphenylacetylene, and solid mixtures of these complexes with suitable, additional carbon sources are heated in a vessel. More specifically, the heating of the transition metal complex is completed at a temperature between 400-800° C. and more particularly 550-700° C. for between 0.1 to 24 hours and more particularly 0.5-3 hours in a sealed vessel under a partial pressure of argon or helium.
